The magnetic roller measures the magnetic field strength of the magnets used inside mag rollers in electrophotographic printers. This key component meters and delivers a uniform layer of toner to the development zone and controls the amount of toner delivered onto the photoreceptor. The magnetic field around the roller must be properly designed and carefully controlled to prevent poor tone reproduction and background toner development. Excellent mag roller function is essential to high-quality prints.
MFA-2000L’s broad array of measurements are made with the click of a button in the easy-to-use software interface.
MFA-2000L:
- Compact, portable design
- Easy-to-use software interface
- Runs on PC with Windows® 7 to 10 OS, 64-bit
- Measurements in the axial direction show uniformity of magnet strength; in the radial direction they show peak flux magnitude and pole angle
- False-color mapping quantifies flux intensity over entire magnet surface, allowing easy spotting of defects
- Quantifies magnets 7.5mm to 17mm in diameter, maximum length 360mm (including shafts)
Typical applications:
- Printer Manufacturers: Incoming inspection of magnets; R&D and prototyping magnets
- Printer R&D: Aid in the design and prototyping for mag roller magnets
- Magnet manufacturers: Supply customers automated QC reports
- Cartridge manufacturers and remanufacturers: Qualify second (or third) sources for your magnets without sacrificing quality
